Can schedule a new kernel?

Eric Antunes — Thu, 02 Dec 2004 11:56:19 GMT

I need to change 2 parameters from the kernel, can I schedule this modification to 04:00 AM for exemple? How to do this??

Thanks,

Eric

If the kernel needs reboot after the modifications, you can basically compile it now and set the reboot in crontab to 4am

Eric,

One thing you can do, though it has some inherent risk, is to use SAM to build your kernel, move it into place but delay the reboot (at least you used to be able to do this with SAM - I haven't tried it in quite a while). Then you schedule an at job to do the reboot at 0400:

at 0400 tomorrow
cd /
shutdown -r -y 0

Hi Eric,
Yes you can configure a new kernel, with cron schedule a reboot...
But after configuring a new kernel dont forget to use kmupdate ! (man kmupdate...)

All the best
Victor
